Another Lifebook machine that needs the same quirk as other similar models to make the driver working.

Input: elantech - force needed quirks on Fujitsu H760

2016-10-04T00:31:57+00:00

Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with the same quirks. Without this patch, the touchpad is useless out-of-the-box as the mouse pointer won't move. This patch makes the driver aware of both the crc_enabled=1 requirement and the middle button, making the touchpad fully functional out-of-the-box.
